Meghan Markle gave up these style favourites upon joining the Royal Family

MEGHAN Markle had to learn a whole new set of rules upon joining the Royal Family after marrying Prince Harry on May 19, which forced the newly appointed Duchess of Sussex to leave behind four beloved style habits.

Meghan, 5ft 6in tall, is seven inches shorter than her husband, who stands at 6ft 1in.

Mr Gratton told the MailOnline: "Couples with a big height difference look slightly unbalanced in pictures, and often the smaller of the two ends up looking even smaller and is constantly looking up at their partner.

"Rod Stewart and his wife Penny have a large gap but this is minimised by Rod wearing Cuban heels and Penny not wearing super high heels.

"In the case of Harry and Meghan she will be wearing high heels to maximise her height and shorten the gap if possible.

“Careful use of wardrobe choices will be important for Harry and Meghan to make sure the couples' height difference is minimised.”
